Explanation:
When you dissolve ammonium chloride crystals in water (H2O), the ammonium chloride compound decomposes into its component ions: NH4+ and Cl-. The dissociation chemical reaction is: NH4Cl(solid) = NH4+(aqueous) + Cl-(aqueous). NH4+(aqueous) +H2O(liquid) = NH3(aqueous) +H3O+(aqueous) H3O+ +OH- = 2H2O.
